This is a spin off of #538 - the arm binaries distributed with JNA are build for armv6l hardfloat. At runtime the ABI needs to be determined and the right binary be loaded:

sun.arch.abi is not present on openJDK

Currently best looking option: use readelf to read the Tag_ABI_VFP_args from the java binary running the current process.

Add arm softfloat variant as platform armel
f482b8e 
- add prebuild arm softfloat binaries
- add option to override prefix detection by specifying jna.prefix
- add prefix autodetection to platform code. Autodetection depends
  on the presence of readelf
- adjust build.xml to implement prefix detection
